Which quadratic function has a leading coefficient of 2 and a constant term of –3?

Romashka [77]

The answer is f(x) = 2x2 + 3x – 3

f(x) = ax² + bx + c
a - the leading coefficient
c - the constant term

We are looking for a = 2, c = -3

Through the process of elimination:
The first (f(x) = 2x3 – 3) and the third choice (f(x) = –3x3 + 2) have x³ so these are not quadratic function.

In the function: f(x) = –3x2 – 3x + 2
a = -3
c = 2

In the function: f(x) = 2x2 + 3x – 3
a = 2
c = -3

Answer:

B. $y=-3x+50$

Step-by-step explanation:

Let x be number of days and y be value of card.

It has been given that your parents gave you a gift card for your favorite coffee shop. The card was worth $50 when you got it. Each day, you buy a drink for $3.

We can see that value of card is dependent on number of days as value of card decrease by 3 each day. This means that slope of our line will be -3.

As initially you have $50, this means that y-intercept of our given line will be 50.

Since we know that equation of a line in slope-intercept form is: $y=mx+b$ , where,
